I am a UK national and want to visit Norway. Do I have to apply for a visitor visa to travel to Norway?
No. UK nationals may enter and stay in Norway and the Schengen area without a visa. You can stay in the Schengen area for up to 90 days during any period of 180 days. If you need to stay longer than 90 days, you must apply for a residence permit.
Note that as long as Norway has entry restrictions due to the corona situation, UK nationals living in the UK will from 1 January 2021 be subject to the regulations that apply to citizens outside the EU/EEA who live in a country outside the EU/EEA.
If you are a UK national residing in an EU/EEA country (not the United Kingdom), the rules for citizens living in an EU/EEA country apply to you.
